Can 2-Bromo-2-methylpentane be matched by the formula C6H13Br alone?

No. C6H13Br covers multiple constitutional isomers. CAS 4283-80-1 identifies the branched structure with bromine on a tertiary carbon, which is not equivalent to other bromomethylpentanes or bromohexanes. Confirm the full name, CAS number, structure and an agreed GC identity method when matching material.

2-Bromo-2-methylpentane CAS 4283-80-1

2-Bromo-2-methylpentane (CAS 4283-80-1), also called tert-Hexyl bromide, is a tertiary alkyl bromide used in controlled tertiary-alkylation, solvolysis, elimination and mechanistic synthesis. Confirm GC assay, alkene and rearrangement impurities, acidity, water, color and residual starting material against the current COA and SDS.

Item	Technical guidance
Product identity	2-Bromo-2-methylpentane; tert-hexyl bromide
CAS / EC	4283-80-1 / 224-287-9
Formula / molecular weight	C₆H₁₃Br / 165.07 g/mol
Reaction character	Tertiary alkyl bromide with condition-dependent ionization, substitution and elimination behavior
Key purchase controls	Identity, GC assay, alkene and rearrangement impurities, acidity or HBr, water, color and residual starting material

Applications and grade selection

2-Bromo-2-methylpentane may be evaluated in controlled tertiary-alkylation, solvolysis, elimination or mechanistic synthesis work.

Set GC assay and limits for alkenes, rearranged species, starting alcohol or hydrocarbon, acidity and water.
Run the intended reaction at small scale to compare substitution, elimination, conversion and downstream work-up.
Confirm compatible packaging, temperature control, dangerous-goods classification and delivery conditions.

Storage and handling

Keep the product tightly closed in compatible packaging away from heat, ignition sources, bases, oxidizers and moisture under the conditions stated in the current SDS. Minimize repeated opening and monitor any color or acidity change.

Safety, documentation and procurement

Handle as a flammable, reactive organobromine intermediate using suitable ventilation, bonding or grounding where required, gloves and eye protection. Procurement should define specification, reaction, quantity, packaging, destination and shipping documentation.
